All I'm saying is it's not exactly "easy", like I don't think they're intentionally blocking this for anti competitive reasons, I bet it's more so cost of development, with an added benefit of driving purchases of proprietary accessories. Bluetooth is a terrible stack that's super difficult to implement
When I first got a PS4 and tried to connect my headset to it I was told of was unsupported. After doing some digging I found that the only supported bluetooth headsets were specifically the ones that were branded as PlayStation. This wasn't the case with the PS3, it was just a decision Sony made in order to sell their overpriced headsets.
The PS5 already have Bluetooth capabilities that are limited artificially by Sony.
The sole reason for that is greed. It is dumb as hell that you need a Bluetooth dongle on a machine that has Bluetooth in order to use a Bluetooth headset of your choice.
I know, but a dongle is very cheap and most good headsets come with dongles. It's not super big deal. I understand it isn't ethical but I just don't see this preventing anyone from buying another headset they actually like.
I had similar, my Bluetooth headphones that I'd been using with the PS3 didn't work on my PS4, but I think the reason given was that they didn't support Bluetooth encryption standards or something.
Like bro, I do not care if someone eavesdrops the audio of my Kingdom Hearts session - just give me the choice
I don't know enough about this really to speak on it, but I think if there was a problem with encryption, a person could spoof a connection to your device and get your passwords or other data maybe. There was a big data leak a few years ago from someone getting into a network through a smart fridge or similar device because of weak security standards.
So having enough of the Bluetooth stack implemented to do a controller is very different than having the audio portions of the Bluetooth stack implemented as well. It's not a "one and done solution", it's more like a big mess
